Chapter 22 Physics Question Paper

6. The mass number is equal to an atom’s number of protons and neutrons added together.

I can use these three values to characterize the structure, charge, and the mass of an atom by using the knowledge I know already. In the problem this atom has 3 protons so its atomic number will be 3 and its mass number equal the number of protons plus number of neutrons equal which you can write like this 3 + 4. The problem 3 + 4 will equal 7. This atom also has 3 electrons, balancing the charge of 3 protons that exist in its nucleus, concluding that this atom has an atomic number of 3 and a mass number 7. The element is

A car in a roller coaster moves along a track that consists of a sequence of ups and downs. Let the x

Every element is special because none are ever the same. Even an atoms isotope is different. Krypton’s atomic number is 36. Its atomic mass is 83.798 units. The number of protons in an element, which is also the atomic number, is 36. It also

Light passed through a transmission grating is often sent in all directions due to interference. The grating acts as a new wave source and causes the light to travel in different paths. Equation 1 below shows the relationship between path difference and light direction due to constructive interference. D represents the line spacing and sinƟ=a/c according to the drawing below.

1. Infer whether the size of an object’s displacement (amount of units between start and stop) could be greater than the distance the object travels.

Task Description:The world communicates by making extensive use of the electromagnetic spectrum. For the average person this is commonly accessed using radio waves. These radio waves may be over the AM or FM radio wave bands or the radio waves that transmit our television signals. Not only are people always within a ‘phone call of each other anywhere in the world they are also able to find out exactly where in the world they are by use of

The year is 5024 and everyone in the class is an archaeologist. You should work in teams of two and take a look at the findings and make guesses about the nature of the findings. This is a very difficult task because nothing is known of life before the year 3500.

Life is about challenging yourself intellectually in order to succeed. I had to challenge myself intellectually in my Physics 11 class. Physics 11 involves a lot critical thinking and connection making in order to understand the concepts. Also, my teacher didn't speak fluent English which made it very difficult to understand, and he didn't give any notes either. I had to adjust to how my teacher taught us, which was difficult, but it helped challenge me intellectually. I made a decision to do as much work as I needed to do well in this class. Every class I made my own notes and reviewed them at home. The textbook I received from my teacher, I used to investigate key ideas for the chapter we learned that day. At home I did the questions the

This is how you can calculate the average atomic mass; multiply the fraction by the mass number for each isotope, then add them together.

Tungsten’s atomic mass is 183.85 g.mol -1 and it has a density of 19.3 g.cm -3 at 20℃.

1. Heat passes through the atmosphere by way of radiation, conduction, and convection. Radiation is heat provided directly by the sun Radiant energy is another word for radiation. Energy from the sun travels on a direct path through space to earth in the form of electromagnetic waves. For example, that heat you feel from the sun while outside when it is blazing down on you is actually radiation. Conduction is the movement of heat inside of an object on a molecular level. When met by a heated outside influence, the atoms begin to vibrate as they warm. As they vibrate, they bounce off one another and each atom passes heat on to another every time they touch. While this is happening, the entire object becomes heated. For example, think of a teakettle. By itself, the kettle remains quite cool. As someone places the kettle onto a lit burner of a stove, the molecules that make up kettle begin to shake rapidly. As the particles run into one another, the entire kettle becomes
